1997 Kia Sephia Problems

What owners report

Owners of this model year most often report brake problems — repeated rotor warping, vibration and a low pedal — and engine stalling that occurs without warning while driving or when pulling away from a stop. A separate, well-documented pattern involves the dashboard lifting, warping or cracking and interfering with the defroster, with some owners worried about the passenger airbag area. These reports span the whole life of the car, from well under 20,000 miles to over 100,000.

1. 1
   Brakes

   Warped front rotors, vibration and low brake pedal

   • 52 complaints (25%)
   • typically at 2.8 yrs old
   • 2 mention a crash, fire or injury
   • filed 1998–2003

   Complaints describe front brake rotors warping repeatedly, with pulsation or heavy vibration through the pedal and, in some cases, extended stopping distance. Several owners say rotors and pads were replaced multiple times, sometimes within a couple of years or tens of thousands of miles, and the problem returned. Others describe the brake pedal traveling close to the floor; according to complaints, dealers variously replaced parts, said the pedal feel was normal, or told owners there was nothing further to do. Reported from roughly 21,000 to 36,000 miles in the sampled complaints, and in some cases within months of purchase.

   1 related service bulletin

   What to check: Have the front rotors and pads inspected for scoring, uneven wear or a lip, and ask for service records showing how often they were replaced. On a test drive, brake firmly from highway speed and note any pulsation, grinding or a pedal that sinks toward the floor.

   “The last time my rotors warped for the fifth time, my dealer wasn't going to replaced them until I had a lengthy discussion with him and he called the manufacturer. He did not replace the brake pads this time because Kia would not authorize that expense. They are warping again for the sixth time. I have never had a car with as many problems as this car(some are not listed). I don't feel safe in it at all.”

   NHTSA complaint #746838, filed 2001-06

   “While driving about any MPH vehicle will suddenly accelerate without a prior warning.consumer will step on brakes pedal to stop acceleration, but vehicle will not stop, and concerned about fact of an accident. Transmission failed. Brakes make noise due to rotor failure. Wiper blades failed. Battery failed.”

   Engine cooling

   Engine stalls or shuts off without warning

   • 26 complaints (13%)
   • median 69,000 mi at 6.8 yrs old (3 state mileage, few)
   • 2 mention a crash, fire or injury
   • filed 1997–2006

   Owners describe the engine cutting out at speed, when braking, when the clutch is engaged, or when pulling away from a stop, sometimes after restarting normally and sometimes leaving the driver stranded. Complaints mention repeated dealer visits with no confirmed cause; a few note the check engine light was on, and one owner says replacing engine wiring harness components resolved the stalling. Reported across a wide mileage range, from around 36,000 to 69,000 miles in the sampled complaints, with some owners reporting it early in ownership.

   What to check: Ask whether the stalling has ever been diagnosed and what was replaced, and whether the check engine light is currently on. Check for stored fault codes and inspect the engine wiring and idle behavior during a long test drive, including stops and clutch use.

   “While driving at any speed, vehicle completely shutsdown without warning, dealer has yet to be contatced. Consumer said when he purchased the vehicle engine light was on and engine shuts off whenever stopping, took back to dealer many times for repair, vehicle is experiencing the same problem. Consumer also stated the speedometer is acting erractically, the overdrive light has illuminated.”

   NHTSA complaint #8000812, filed 2001-12

   “While driving and applying the brakes engine stalls completely out. Has to be turned off and started back up. Dealer has seen vehicle, and cant find solution.”

   Body and structure

   Dashboard warping, lifting or cracking

   • 15 complaints (7%)
   • median 72,000 mi at 6.3 yrs old (7 state mileage, few)
   • 1 mention a crash, fire or injury
   • filed 2001–2007

   Complaints describe the top of the dashboard curling, lifting away from the windshield or frame, or developing burned-looking spots and cracks, sometimes with a film on the inside of the glass and an odor. Owners report that the lifted dash interferes with the defroster vents, so windows clear poorly, and some raise concern about the passenger-side airbag area being exposed. According to the complaints, dealers offered little or no remedy. Reported from roughly 22,000 to 110,000 miles, and in one case on a car with very low mileage.

   What to check: Look along the base of the windshield for a gap, curl or stretch marks, and check that the defroster vents sit flush and blow air across the glass. Test the heater and defroster on a cool, humid morning.

   “The dashboard is warped/coming up and has bent/ruined the defrost/defogger system. It happened all on it's own, we did nothing to provoke this. I am the original owner and the car has never been in a wreck. I am concerned if it has caused airbag damage. It is a hazard not to be able to defrost/defog windows. Also the tailpipe keeps getting holes in it and we have to keep getting welding done on it.”

   NHTSA complaint #10203109, filed 2007-09, 49,000 miles

   “The dashboard on this year vehicle starts to curl and is heading towards the passenger side airbag which may pop and cause injuries or fatalities. The dashboard also breaks the plastic vents which then does not distribute the air on the defroster properly which then could also cause fatalities or injuries.”

   Air bags

   Airbags not deploying in a collision

   • 28 complaints (14%)
   • median 47,295 mi at 6.9 yrs old (4 state mileage, few)
   • 20 mention a crash, fire or injury
   • filed 1996–2007

   Several owners report that the airbags did not deploy in front-end collisions, including impacts severe enough to total the vehicle, and one reports airbags deploying about a week after a crash. Complaints also describe the airbag warning light staying on and dealers saying there was nothing to do outside warranty or that the sensor repair would be at the owner's cost. One case notes late deployment after a collision. Reported across a range of mileages, including a car with about 18,000 miles showing the airbag light.

   What to check: With the ignition on, confirm the airbag warning light comes on and then goes out. Ask for any history of airbag sensor or module work and whether the warning light has been on at any point.

   “Dt: consumer's vehicle was hit by another car on august 15, 2005, and the airbags failed to deploy. Were still unsure of the extend of the injuries to the consumer. A police report was taken. The manufacturer was unhelpful to the consumer. They told the consumer that the airbags should not have deployed under these circumstances. Although other information they sent her said that the air bags should have deployed.”

   NHTSA complaint #10137621, filed 2005-09, 100,000 miles

   “Dual air bags did not deploy and front and rear passnger's seat belt assembly did not restrain, allowing driver's chest to impact steering and css to be thrown forward. Injuries: back, neck.head and concussions from css straps.”

   Seat belts

   Seat belts unlatching or detaching

   • 7 complaints (3%)
   • typically at 4.8 yrs old
   • 3 mention a crash, fire or injury
   • filed 1999–2005

   Owners report front buckles that fail to latch properly and release unexpectedly, and rear belt anchor points that came apart from the wall mount when the car stopped suddenly. One complaint describes a rear shoulder belt tightening to the point that it had to be cut off a child. The front buckle concern corresponds to recall 02V216000, which addresses buckles that may falsely latch. Reported on vehicles of varying age, including cars only a couple of years old at the time of the complaint.

   Recall 02V216000

   What to check: Check whether recall 02V216000 was performed on the vehicle, and test every buckle by inserting and tugging the latch plate firmly; also pull on the rear belt anchor points to confirm they are secure.

   “Rear passenger's seat belt detached from wall mount upon suddenly stopping vehicle, injuring child's head. Upon inspecting the rear driver's side belt, discovered the same connector piece was coming unattached.”

   NHTSA complaint #524291, filed 1997-11

   “Driver's seat belt buckle does not latch on properly,and unbuckles unexpectedly when moving around, which wont protect the occupant in event of a crash. Please provide further information and VIN#.”

   NHTSA complaint #837509, filed 1999-05

Buying note. This model year draws recurring brake, stalling and dashboard reports, so a pre-purchase inspection focused on the brakes, engine fault codes and dash fit is worth the cost. Confirm the seat belt buckle recall was completed and check that the airbag warning light behaves normally before buying.
